Does cousin marriage cause genetic problems?

Contrary to widely held beliefs and longstanding taboos in America, first cousins can safely have children together, without a great risk of birth defects or genetic disease, scientists are reporting today. They say there is no biological reason to discourage cousins from marrying.

Why consanguineous marriage shows more autosomal recessive disorders?

The high consanguinity rates, coupled by the large family size in some communities, could induce the expression of autosomal recessive diseases, including very rare or new syndromes which increase the public awareness of the risks associated with consanguineous marriages.

What are the benefits of cousin marriage?

Cultures where cousin marriage is common point to its social and economic benefits, such as strengthening family ties and keeping wealth in the family. Opponents argue that first cousin marriage increases the risk of passing on genetic abnormalities.

Can marrying a cousin cause birth defects?

Why is consanguineous important when discussing recessive genetic disorders?

Individuals who are blood relatives are more likely to be silent carriers for the same recessive condition(s), hence the risk of autosomal recessive genetic disorders is higher in children born from consanguineous unions.

Why are genetic disorders more common in the offspring of consanguineous partners?

The offspring of consanguineous unions may be at increased risk to genetic disorders because of the expression of autosomal recessive gene mutations inherited from a common ancestor.

What are the disadvantages of marrying your cousin?

Marriage between first cousins doubles risk of birth defects, say researchers. Marriage between first cousins doubles the risk of children being born with birth defects, according to a study seeking answers to the higher than expected rates of deaths and congenital abnormalities in the babies of the Pakistani community …

Why you shouldn’t marry your cousin?

Marrying a cousin is usually considered a bad idea, because inbreeding can lead to harmful genetic conditions. But paradoxically, in some societies, marrying a related spouse is linked to having more surviving children, research suggests.

Why close relatives should not marry?
